1. A method of cleaning a hard surface using an on-site generated peroxycarboxylic acid forming composition comprising:
obtaining a user-or system-inputted peroxycarboxylic acid forming composition on-site using an adjustable biocide formulator or generator system comprising: an apparatus comprising a reaction manifold, a series of feed pumps and an outlet for dosing a peroxycarboxylic acid forming composition from said reaction manifold; and
applying said peroxycarboxylic acid forming composition in an amount sufficient to sanitize, bleach and/or disinfect a hard surface in need thereof,
wherein said reaction manifold is a length of tubing having multiple points of input via at least one injection manifold wherein said feed pumps provide said reagents for the continuous production of said peroxycarboxylic acid forming composition;
wherein said feed pumps are in fluid connection with said reaction manifold and supply said reagents to produce said peroxycarboxylic acid forming composition in said reaction manifold;
wherein said reagents comprise the following three reagents: (1) a sugar ester, (2) a source of alkalinity, and (3) an oxidizing agent;
wherein said reaction manifold is in fluid connection with said outlet to dispense said peroxycarboxylic acid forming composition;
wherein said sugar ester is an ester of a polyhydric alcohol and a C1 to C18 carboxylic acid; and
wherein said peroxycarboxylic acid forming composition is an individual or mixed peroxycarboxylic acid forming composition according to a user-or system-inputted selection.
